AM4378: SPI CS issue

Tanner Hunsucker73

Part Number: AM4378
Other Parts Discussed in Thread: AM4372

Hello,

I am using the spi-omap2-mcspi driver in Linux SDK version 4.3.0.5. I am trying to complete a SPI transfer, and the chip select should be driven low during this transfer. Instead, the chip select stays high and never is driven low. In the spi-omap2-mcspi.c file, I added a printk call in the omap2_mcspi_set_cs() function, so I can see that this function is called when a transfer is supposed to begin. I can also see that the force bit in the mcspi_chconf register is being set to 1. Any ideas on why the chip select isn't being set to 0?

Hi,

One possible reason is incorrect pinmuxing of the CS pin.

I think I have them pinmuxed correctly, but here it is:

spi_0_pins_default: spi_0_pins_default {
pinctrl-single,pins = <
AM4372_IOPAD(0x950, PIN_INPUT_PULLUP | MUX_MODE0) /* (P23) spi0_sclk.spi0_sclk */
AM4372_IOPAD(0x954, PIN_INPUT | MUX_MODE0) /* (T22) spi0_d0.spi0_d0 */
AM4372_IOPAD(0x958, PIN_OUTPUT | MUX_MODE0) /* (T21) spi0_d1.spi0_d1 */
AM4372_IOPAD(0x95c, PIN_OUTPUT | MUX_MODE0) /* (T20) spi0_cs0.spi0_cs0 */
>;
};

/* Optional sleep pin settings. Must manually enter values in the below skeleton. */
spi_0_pins_sleep: spi_0_pins_sleep {
pinctrl-single,pins = <
AM4372_IOPAD(0x950, PIN_INPUT_PULLUP | MUX_MODE0) /* (P23) spi0_sclk.spi0_sclk */
AM4372_IOPAD(0x954, PIN_INPUT | MUX_MODE0) /* (T22) spi0_d0.spi0_d0 */
AM4372_IOPAD(0x958, PIN_OUTPUT | MUX_MODE0) /* (T21) spi0_d1.spi0_d1 */
AM4372_IOPAD(0x95c, PIN_OUTPUT | MUX_MODE0) /* (T20) spi0_cs0.spi0_cs0 */
>;
};

And here is the spi node. Let me know if you see anything that doesn't look right.

&spi0 {
compatible = "ti,omap4-mcspi";
status = "okay";

pinctrl-names = "default", "sleep";
pinctrl-0 = <&spi_0_pins_default>;
pinctrl-1 = <&spi_0_pins_sleep>;

#address-cells = <1>;
#size-cells = <0>;
ti,spi-num-cs = <1>;
ti,hwmods = "spi0";

dmas = <&edma 16 0
&edma 17 0>;
dma-names = "tx0", "rx0";

spidev@0 {
compatible = "rohm,dh2228fv";
spi-max-frequency = <9000000>;
reg = <0x0>;
};
};

Hi Tanner,

the SDK you are using is 2 years old. Can you please try the current Linux SDK for AM437x to see if that makes any difference. More often than not general bug fixes and improvements in the Kernel tree over time can make a difference:

http://software-dl.ti.com/processor-sdk-linux/esd/AM437X/latest/index_FDS.html

Then, the Kernel v4.19 part of this SDK also has an AM437x-based SPI0 example including pinmux which you can leverage and use as a reference for hopefully a known-good starting point:

https://git.ti.com/cgit/processor-sdk/processor-sdk-linux/tree/arch/arm/boot/dts/am437x-cm-t43.dts?h=processor-sdk-linux-4.19.y#n300

It's been a while since I've started from scratch with a new SDK. I downloaded it and ran the startup script, but I think I need to build the SDK as well, correct? I'm following the steps here and I tried running the bitbake command, but it fails with an error saying that it needs to use a python version > 2.7. But I have python 2.7 and 3.5 installed on my machine. I remembered that there was a patch related to python that I needed to run when I built the last SDK, and I tried running it again for the new SDK but it failed with the following errors:

error: meta/recipes-devtools/python/python-3.5-manifest.inc: No such file or directory
error: meta/recipes-devtools/python/python3_3.5.2.bb: No such file or directory

Is there a new patch for the newer SDK?

Hi Tanner,

for a quick test I would just do the following:

Create an SD card image with the SDK-included bin/create-sdcard.sh script
Manually build the Kernel (currently v4.19) from the folder that is part of the SDK after you updated the kernel configuration (create SDK config baseline via the ti_config_fragments/defconfig_builder.sh script in the Kernel directory) and DTS files per your needs - all the steps involved are standard
Populate/install the new Kernel, DTB files, and modules onto the SD card image created earlier

As for building the entire image using Yocto/Bitbake, it may be good first trying out the steps from the documentation you found on a clean machine with a compatible Ubuntu image. Alternatively, use a VM inside your current machine for building (VirtualBox is free). Once you have this working you should be able to debug the issue you are seeing with Python by comparing against this known-good reference, probably also involving some online research.

I am using a custom board so there are also a lot of U-Boot changes that I need to make in order to get it working with the new SDK. Eventually I think it is a good idea to update to the new one, but I can't get my custom U-Boot stuff working and I don't really want to spend a ton of time looking into it right now if it's not necessary.

Do you think that the older SDK is actually my problem? I understand that it is two years old but I have to imagine the SPI driver should still work with that SDK... I never got an answer about how my device tree looks - I think it looks pretty similar to the example you gave me, and all of the pinmuxing looks correct.

Hi Tanner,

Tanner Hunsucker73 said:

Probably not but I am using the current SDK here and wanted to make sure we are looking at the same baseline as things such as DTS declarations/requirements sometimes change between Kernel versions (so we don't have another variable here).

Your DTS looks good I think from the point of the current SDK although I don't know why you re-declare 'compatible' (shouldn't hurt though).

A few things...

Can you post a copy of your bootlog.
Can you post a de-compiled version of your final DTB file (basically, run "dtc -I dtb your_dtb_file_name_here.dts > final_device_tree.dts") so we can look at everything that went in there throughout its entire include hierarchy.
Then, can you post the output of 'cat /sys/kernel/debug/pinctrl/44e10800.pinmux-pinctrl-single/pinmux-pins'

Hi Andreas,

In regards to the SDK versions, that makes sense in terms of eliminating a variable between our setups. I have still been trying to update to the newest version, but the more I get into it the more I remember the amount of U-Boot changes I needed to make. Some of which were some patches related to DDR that were provided to me by TI, but it appears those patches are no longer available. So in order to get that working I probably am going to need to create another E2E thread just related to that issue.

I have attached a copy of my bootlog and the output to #3. However, when I tried to run the command in #2, I got the following error: FATAL ERROR: Blob has incorrect magic number.

Hi Tanner,

my apologies that command should have read "dtc -I dtb your_dtb_file_name_here.dtb". Basically, you feeding in your final DTB file, and it will get de-compiled into an DTS file. Can you please try that again.

Regards, Andreas

Yep, here is the output file.

TI__Guru 70192 points

Thanks for the info. Looks okay at first glance. Give me a day or two to look into this a bit deeper.

Also how do you initiate the SPI transfer? May need to see if I can re-create what you are doing.

Regards, Andreas

0 Tanner Hunsucker73 over 5 years ago in reply to Andreas Dannenberg

Expert 2190 points

The SPI transfer is initiated by doing a write to the /dev/spidev1.0 file.

Tanner,

I did a quick test by doing the following:

Using an AM437x GP EVM
That EVM has the SPI0 D0 (data input) exposed via pin header, and SCLK is accessible by probing the board directly. Unfortunately there is no easy access to CS as the associated pin/signal is heavily used.
I've jumpered the D0 signal first to 3.3V, did a read from spidev, then jumpered it to 0V, and did another read. You can see below how the data that is read (4 bytes) changes from 0xff to 0x00 as expected
I've also used a logic analyzer probing the sclk signal during those transactions, and I could see the clock coming on and off. So this piece is working too.

Below are the changes I did to the TI Linux Kernel 4.19 tree to do this test (the defconfig is more for completeness sake than anything, all I did over the TI default defconfig is adding CONFIG_SPI_SPIDEV=y). Can you see that you can re-create this on your end? If the read works then I'd expect the chipselect signal to go along with it, which again is a particular aspect I could not test with my HW. It also may be worth reviewing Documentation/spi/spidev in the Kernel in detail to make sure nothing is missing in terms of how to use spidev.

Regards, Andreas

This test doesn't really help me with my issue. When I try to do a SPI read, I can see the clock going just the same as you can. But even though the clock is going, the chip select still doesn't go low. If you change D0 manually I can see that a read would work, but if the SPI device is waiting for chip select to go low before it does a write then it will never do the write, correct?

Of course CS needs to be asserted correctly. I don't have any HW where I could access the signal so what I described earlier was about the extend of testing I could do quickly. Might be able to try using a different SPI module other than SPI0 if you think that would be useful but I won't be able to look into this until later this week or early next week.

I ran a test where I do a printout every time the FORCE bit is set in the ch0conf register, and every time the ENABLE bit is set in the ch0ctrl register. The following is the printout I got when I do a read:

[ 269.067835] force=1
[ 269.070046] enable=0
[ 269.072416] enable=1
[ 269.078912] enable=0
[ 269.081295] enable=1
[ 269.083575] enable=0
[ 269.090125] enable=0
[ 269.092837] enable=0
[ 269.098705] enable=1
[ 269.101098] enable=0
[ 269.103523] enable=1
[ 269.110155] enable=0
[ 269.112540] enable=0
[ 269.117521] force=0

Does this look right to you?It would seem to me like the force bit is doing what it should, but should the enable bit be flipping back and forth like this during a read? I don't really understand the relationship between SPIEN and CS.

Hi Tanner,

thanks for sharing those observations. For all practical purposes I would assume the driver to be a known-good entity so that's not the place where I would start debugging. However I had another look at the document I pointed to earlier and found this:

https://git.ti.com/cgit/processor-sdk/processor-sdk-linux/tree/Documentation/spi/spidev?h=processor-sdk-linux-4.19.y

Standard read() and write() operations are obviously only half-duplex, and
the chipselect is deactivated between those operations.  Full-duplex access,
and composite operation without chipselect de-activation, is available using
the SPI_IOC_MESSAGE(N) request.

From this it seems like you need to access the /dev/spidev device on a lower level (through C code) than you can by just writing to it using a shell. There are actually two example programs part of the Kernel tree that you can build that do just that, allowing you to control various parameters via command line options.

spidev_fdx.c

https://git.ti.com/cgit/processor-sdk/processor-sdk-linux/tree/tools/spi/spidev_fdx.c?h=processor-sdk-linux-4.19.y

spidev_test.c

https://git.ti.com/cgit/processor-sdk/processor-sdk-linux/tree/tools/spi/spidev_test.c?h=processor-sdk-linux-4.19.y

Can you try those out and see if now the CS signal is behaving as expected?

Regards, Andreas
